Wet logs are unsuitable for burning, as they do not produce enough heat and all of the
energy is lost in the process of evaporation. Moreover, the burning of wet wood causes
badly smelling gases to be released and a thick layer of tar will deposit on the stove
panels and in the chimney.
Brown coal briquettes
Brown coal briquettes burn in more or less the same way as wood does. You should only
burn briquettes on a bed of charcoal in your stove.
Charcoal
There are several categories of anthracite coal. Some characteristics may be legally
determined. For instance anthracite "A" has to contain less than 10% of volatile
substances, anthracite "B" less than 12%. The ash content may range from 3 to 13%.
For a good operation of your appliance, the use of anthracite "A" with a low ash content
is recommended. A combustible with a high ash content has a lower net heating value.
Moreover, the ashes have to be removed more frequently and the fire will go out faster.
The recommended calibre is 12/22 or 20/30.

Air supply adjustment
For the supply of combustion air, the
appliance is provided with three air
inlets at the back of the appliance, one
of which is adjustable by way of a
handle at the bottom of the front of the
furnace. Through special air vents, this
secondary airflow (2) is conducted to
the top of the glass window. The
primary air intake is controlled by way
of a thermostat at the back. This air
intake regulates the amount of air that
passes through the grating (1). A
sealable air intake at the back of the
combustion chamber (3) ensures a
perfect afterburning (only to be used
for wood) (see images)
